A formula for the area of a triangle is?

Answer 1

base X(mulitply) height / (divided) by 2

Answer 2

A=bh(1/2)

* * * * *

That assumes you know the base and the vertical height. But you may not.

If you know two sides and the included angle, the area is

Area = 0.5*a*b*sin(C)

Or, if you know all three sides, then let s = (a+b+c)/2

then Area = sqrt[s*(s-a)*(s-b)*(s-c)]

There are other formulae. For the formula to be of any use, it must take account of what information you do have. There is no point in having a neat formula if the information required to use it is not available!
Base X Height divided by 2
.5 times the base and the height commonly expressed as bh/2

Answer 3

Area of a triangle= half of the base multiplied by the height.

A = 1/2 (b) (h) <--formula

Answer 4

base x height divided by 2

EX: h=5cm B=10cm

5x10=50 50 divided by 2=25, so A= 25cm2

(always make sure to use 2 when it comes to area)

Answer 5

Area of a triangle = 0.5*base*height

Answer 6

The base is 9cm, 7cm, h20
